Zinc Sulfate Heptahydrate 99% – Essential Micronutrient for Agriculture, Animal Nutrition & Industry
We supply premium zinc sulfate heptahydrate with a 99% purity guarantee. This high-quality salt provides a highly bioavailable source of zinc and sulfur. Consequently, the agricultural, feed, and industrial sectors actively use it to correct deficiencies and enhance product performance. Moreover, its excellent solubility and purity make it a fundamental raw material for health and manufacturing applications.
Core Industrial Applications and Uses
This versatile compound delivers vital functionality in three primary markets. Its roles are specific yet critically important.
First, the agricultural industry relies on zinc sulfate as a high-efficiency micronutrient fertilizer. It rapidly corrects zinc deficiency in soils, thereby improving crop yield, plant vigor, and resistance to disease. Therefore, farmers and agronomists use it for cereals, fruits, and vegetables to ensure optimal growth and harvest quality.
Second, the animal feed industry formulates with it as a key nutritional supplement. It is essential for proper metabolism, skin health, and immune function in livestock, poultry, and aquaculture. Furthermore, feed manufacturers depend on its consistent quality to produce balanced premixes and complete feeds.
Third, numerous industrial processes utilize it as a critical chemical reagent. For example, the textile industry uses it as a mordant in dyeing, while the chemical sector employs it to produce other zinc compounds. Additionally, it is used in electrolyte solutions for zinc plating, as a coagulant in rayon production, and in wood preservatives.
